The "stop command" is waiting for its end, if the role should have a special parameters for waiting it ?
It's seems that ansible role is terminate before activeMq end successful...

Answer 1

This message is a problem and indicates that you are running a JDK older than JDK 8. ActiveMQ 5.15.x needs JDK 8 as a minimum.
Unsupported major.minor version 52.0
